Answer 1

Explicación paso a paso:

L1 ) 7x + 1 = 4x – 3

7x – 4x = – 3 – 1

3x = – 4

x = –4/3

U ) 5x + 1 = 16

5x = 16 – 1

5x = 15

x = 15/5

x = 3

O1 ) 2 (x+1) + 4 = 3 (x–4)

2x + 2 + 4 = 3x – 12

2x – 3x = – 12 – 6

–x = – 18 /×-1

x = 18

C ) 8x + 2 = x + 3

8x – x = 3 – 2

7x = 1

x = 1/7

L2 ) 5x – 9 = 2x + 3

5x – 2x = 3 + 9

3x = 12

x = 12/3

x = 4

O2 ) 5 (3x–1) – 8x = 5x + 11

15x – 5 – 8x = 5x + 11

15x – 8x – 5x = 11 + 5

2x = 16

x = 16/2

x = 8

1. 18. ===== O1
2. –4/3 ===== L1
3. 4 ===== L2
4. 3 ==== U
5. 1/7 === C
6. 8. ==== O2
